Application filed April 20, 1910. Serial No. 556,621.

To all whom z'zf may concern.'

it knownV that I, HAROLD C. Pnasn, av

citiilen of the Unit-ed States, residing at Schenectady, in the county of Schenectady due to lack of lubricant and to prevent the i lubricant from coming in contact with parts which would be injured thereby.

The invention is susceptible of use in many and widely different relations and is in no way restricted as to its application; thus it may be employed to advantage in connection with bearings for a rotary shaft to prevent the escape of oil therefrom and in packings for various uses. ln practice l have found it of particular utility in connection with the hearings for the drive shaft of Van automobile where it not only effects a saving of oil and insures proper operation, but also prevents the oil from spreading over parts exterior to the bearing, such as 'the brakes, which would be injured thereby.

The invention resides in the employment of glycerin in a bearing or packing to prevent a lubricating oil from working out through the space between a moving and a relatively stationary part. Suitable material is employed for holding the glycerin, as for instance a body of'a porous or fibrous absorbent substance which may be impregnated with the glycerin. In the preferred embodiment of the invention, an annulla of such a porous or fibrous substance as leather or felt is provided at one or both sides of a bearing, this being impregnated with glycerin and having the rotary shaft which is journaled in the bearlng passing through theopening therein. The lubricat ing oil with which the bearing is filled contacts with one side of this annulus or oil-retaining packing but will not enter and pass through the same because of the presence of the glycerin therein; also, a thin film of the glycerin will fill into the space between the rot. ry shaft and the felt or leather annulus and prevent the lubricating oil from Work ing along the shaft to the exterior of the bearing.

One embodiment of the invention is illus trated in the accompanying drawing, in Which- Figure l is a longitudinal section of .a bearing for a rotary shaft provided with my improved lubricant retainer, and Fin'. 2 is a transverse section on line 2 2 of Fig, l.

Referring to the drawing, l indicates a rotary shaft and 2 a frame-member formed to provide a bearing for shaft 1.- In the member 2 is a suitable cylindrical chamber 4 having a plurality of steel rollers 3 therein on which shaft l bears. The space around the rollers 3 and between them and shaft l is filled with lubricating oil, through the open-- ing l0 in member 2 shown in Fig. l lead ing to the chamber 4. Member 2 has a boss formed thereon co-axial with shaft l and eX- tericrly threaded so as to receive thereon a cap G provided with an .inwardly turned flange 5, and between this iange and the end of member 2 a steel washer '.7 may be vemployed. At one or both sides of the bean.

ing is a washer or annulus 8 of a porous or fibrous absorbent substance impregnated with glycerin or glycerin and another fluid combined. lPreferably heavy felt is employed for this washer as it can be cut to the desired shape, will retain that shape and will hold therein a substantial quantity of the glycerin. This washer 8 is located be tween the iange 5 and the steel washer 7 and it is of such size'that it I'its closely around the shaft l and within the cap 6. lf desired, more glycerin may be introducedinto the bearing thanwillbe taken up byl washer 8, as indicated. at 9, this being .ef tained therein by iange 5, so that the supply of the glycerin helel by washer 8 will b'e replenished ywhen necessary. By reason of the impregnation of the washerwith glycerin, the lubricating oil-inthe bearing will d"not be absorbed by the washer and allowed to work its way through the same; and enough ofthe glycerin comes out upon the surfaces of the washer to form a thin film between the shaft 1 and cap 6 and the adjacent surfaces of the washers which film prevents the oil 'from passing along the shaft and cap to the exterior of the bearing. rlhe washer 7 of metal is employed for spacing the washer 8 from the bearing and .the rollers 3 as the fibrous washer 8 might become worn if it engaged these parts. The washer 8 is of such sizethat it makes a tight t upon the shaft l and within the cap 6, so
